The objectjof-the invention is to provide a simple andefiicient mechanism for driving -the rotary knitting element and "for "shifting fromon'e motiontothe other with certainty and without shocker .undue'wear up on the parts and to these ends the invention comprises the features Qt -construction and combinadzion of" parts" hereinafter descr bed and ireferredto in theclaims.

V a A mechanism embodying a preferred form of the invention is shown 1n the accompanying drawings in which Fig; 1 1s a vertical sectional view; F-ig 2 "is a transverse sectional elevation on line 2' of Fig.1, and

Fig. 3 is a perspective view otthe ring -36 to' be described. V

The invention isflshown in' thef-drawings applied to a circular knitting machine fully shown andv descrilc'iedin application-"Serial No; 458,640,'filed April 5, 1921; ofwhichf-the present application 'adivision. I This 'ma chine is provided with ai'ot'ary needle cy1- inder Qbarrying needles 4 which are onerated by cams andcontrolling devices carried by a stationary; cam cylinder '6.

The gear ismountedto rotate within 'a vertically movable ring 10 'provided with ribs 12 Which: rest upon "supporting rolls 14L and are held in engagement therewith byrolls 16. The cylindervis rotated and 'reciprocated through a gear 18 ,which'engages the gear 8 and is secured 'uponthe' upper end of a short verticalshaft V 20. -The lower end' ofthe shaft is connected through a beveled gear '22 with a beveled gear 24; wh1ch is formed on theend ot a sleeve 26 loosely mounted. on the (lI1V1 I1g shaft'27.

A motion changing clutch sleeve 28' is keyed to slide: on thesleeveQG and, may be shifted to connect thesleeve26, and there-V fore the needle cylinder, with either a: continously rotating pinion 29 or an oscillating pinion 30. Therotary pinion 29 is'p'inned to the shaft while the oscillating pinion and to shiftthe 'chitch tr'OmDne active position.
